I second Mark's suggestion of CBD oil or at least the closest to a 100% indica strain you can find.

I was a daily smoker before my first concussion. I often used it to medicate my celiac disease. I quit after I had a major panic attack trying to smoke two weeks after that concussion.

I look forward to shops opening up in Oregon so I can pick and choose strains and stay away from those with high THC contents. I'm glad it's helping you! I just figured I'd throw in a warning about THC causing panic.
